Arduino UNO Microcontroller

Internet of Things

• Sensors and actuators embedded in physicalobjects are linked through wired and wirelessnetworks

• The Internet of things is the internetworking ofphysical devices, vehicles, buildings andotheritems—embedded with electronics, software, sensors,actuators, and network connectivity that enablethese objects to collect and exchange data.

Requirements of IOT

• Hardware Requirements– Microcontroller

– Sensors

– GSM Module

– Bluetooth

• Software Requirements– Arduino IDE

Microcontroller

• A microcontroller is a complete computer

system, including a CPU , memory, a clock

oscillator, and I/O on a single integrated

circuit chip.

Arduino UNO Microcontroller

• Arduino is an open-source electronics platform based on easy-to-use hardware and software.

• Arduino boards are able to read inputs and turn it into anoutput.

• By using the Arduino API we can tell the microcontroller boardwhat to do by send the set of instructions to it.

• Arduino can interact with buttons, LEDs, motors, speakers,GPS units, cameras, the internet, and even your smart-phoneor your TV

Features of Arduino UNO

• Digital I/O Pins - 14 (of which 6 provide PWM output)

• Analog Input Pins - 6

• Flash Memory - 32 KB

• SRAM - 2 KB

• EEPROM - 1KB

Arduino Boards

• Various kinds of Arduino boards are availabledepending on different microcontrollers used.

• Boards differ in Operating Voltage, clockspeed, and number of Digital I/O, Analog &PWM pins.

• all Arduino boards have one thing incommon: they are programed through theArduino IDE.

Intel Galileo Gen2 Board

Features of Intel Galileo Gen2

• Microcontroller - SoC Quark X1000

• Operating Voltage - 3.3V / 5V

• Digital I/O Pins - 14 (of which 6 provide 8/12-bit PWM output)

• Analog Input Pins - 6

• Flash Memory - 512 kB

• SRAM - 512 kB

• EEPROM - 8kB

• Clock Speed - 400MHz

Sensors

• A sensor is a device that detects and respondsto some type of input from the physicalenvironment.

• A sensor is a device that sense the data fromphysical environment and converts real worlddata (Analog) into data that a computer canunderstand.

Sensors

• Analog sensors-produce continuous analog output signal and

these sensors are considered as analog sensors

• Ex: light sensors, sound sensors, temperature sensors

• Digital sensors-an electronic or electrochemical sensor,

where data conversion and data transmission are done digitally.

• It has two discrete values. It is on, or it is off.

• Ex: Push button, LED sensors
